|Season||Futari wa Pretty Cure Splash Star|
|Home Place||Dark Fall|
|Japanese Voice Actor||Chiba Isshin|
Karehan first appears to capture Flappy and Choppy to find out where the Fountain of the Sun is. FwPCSS01 He appears shortly after Saki and Mai first meet the mascots and nearly captures them but is then defeated when Saki and Mai become Pretty Cure.
An impatient person, Karehan often gets angry or yells at others. Even when he is not enraged. His tolerance for mocking is also low, but due to this Goyan likes to taunt him for this very reason. He does not like knowing he's probably the weakest member in the group and when he fails, he often hides by himself to think things through before doing anything else.
He has long yellow-white hair that sticks straight up, and wears a leaf mask. He also has yellow eyes.
His name comes from the word "kareha" (枯葉) which means "dried leafs" in Japanese.
- Karehan is the first villain to have the element of trees.
- In DX 2, Arachnea mistakes his name for "kare pan", lit. meaning curry bread.
- In DX 2, he, together with Moerumba, Ms. Shitataare and Kintoleski, represents the villains from Splash Star.
- He is afraid of fire. Which is ironic because he is the element of trees since fire burns trees.
- He is similar to Pisard from the first season, as both are the weakest members of their homes and the first ones to be sent out and defeated.
